To all whom t may cof/wem:

Beit lmown that 1.SAMUEL S. AMDUnsKY, a citizen of the United States,residing at Rochester, State of New York, have invented certain new landuseful Improvements in Automatic Valves; and l do hereby declare"the-follows ing to he a full, clear, and exact description of the same,reference being had to the ac l0 companying drawings, forming a part cithe s ecication, and to the reference numera marked thereon.

This invention relates to valves which are automatically moved in agiven direction on la the occurrence of a predetermined -`condition inthe sup ly line in which these valves are placed. proved means formoving a valve in a given direction on the attainment of a pre eteraumined pressure.

A further object resides in the sim liiication of construction 'and thegenera 'compactness of the automatic means for op.-

erating a valve. To these and other ends, et the invention consists incertain improvements and combinations of parts, all as will beHereinafter more fully described, the novel features being pointed outin the claims at the end of the specification. et In the drawings:

Figure 1 represents a cross sectionalview of a duid pressure line andthe automatic valve operating means with the valve in closed position. ye5 Figure 2 is the same as Figure 1 except that the valve is open. 4

Figure 3 is a top plan view of the valve and automatic means therefor. n

,Figure 4 is a left hand end view of the ce device shown in the'foregoin figures.

Figure 45 is a section on' t e lme 5--5 of Fi res 2 and 3. p

imilar reference characters throughout the several views indicate thesame parts. as The principal features of my invention s comprise thegeneral simplicity and arrangement of parts and the improved automaticvoperating means for a valve in a iuid ressurev line on the attainment ofa pre eter- 50' mined condition in the line or in some other iiuidcontainer connected to the automatic operatingmeans.

Referring to the drawings, a iiuid pressure line is provided with avalve 11 ee therein, adapted to be controlled by the presin thev countyof Monroe and e object is to provide an im' thereof to protect the sureresponsive means .15 contained in the housing 12 which is preferably oibronze or other suitable material, which means acts upon the valve bar13 through suitable connections on the attainment of a predeterminedpressure to move the same to the right, as shown in Figure 2, andoperate the valve by means of the lever 14 attached thereto. An exansible chamber or dia= phragm 1 5, pre. erably corrugated and of metal,as indicated in the drawing so as to be readily expansible, may be incommunication through the passageway 16 with the uid pressure main 10when the diaphragm is to be responswe to pressure in the main or whenresponsive to pressure elsewhere the passageway may lead thereto.Resting against the diaphragm and adapted to be slidablymoved therebyagainst the action of the spring 18 is the yoke member 17, shown moreclearly in Figure 5 which is of suiiicient size to embrace the bar 13and sleeve 23. The spr-in 18 cooperates with the top of the yoke mem er17 and with the adjustable nut 19 located as shown in the top of thehousing 12 and provided with a central aperture 20 therein to aord aguideway forthe slidable stem 21 of the yoke member. .A stop member 22,preferably of steel or other appropriate material, 'is rigidly se' curedon the yoke member, as indicated, .and is adapted to engage a sleeve 23onv the bar 13 when the latter is in the position indicatedin Figure 1where it is shown as retracted against the force of the spring 25, whichcooperates with the casing or housing 12, and with the sleeve 23 vwhichserves to guide the s ring when in com ressed position. The s eeve issecured to the bar 13 by the pin 24, and is alsoadaptedto be engaged byt e stop 22, as shownin Figure 1. A rmaP or other appropriate handle maybe place on theleft end of the bar 13 for convenience in moving the sameto the left or retracted position. The housing 12 may be provided with acap piece 2? s rung over the top justable nut 19. In operation the bar13 is manually re tracted against the action of the spring 25 from theposition shown in Figure 2 to that shown in Figure 1 until there issuilicient pressure in the main 10 to cause the diaphragm 15 to expandand slide the yoke 17 liti .and stop member 22 far enough against theaction of the spring 18 to enable the sleeve ne 23 and bar 13 to becomedisengaged from the stop member 22 4when the spring 25 then moves thebar 13 to the right and operates the valve as shown in Figure 2. Thepressure at which the diaphragm acts to operate the valve is readily andaccurately controlled by the adjustment of nut 19.

One use to which the automatic valve is particularly adapted is inconjunction with fluid supply lines controlled by regulating devicesresponsive to pressure for various processes. Some regulating devices'of this character do not function to best advantage at partialpressures While full pressure is being built up in the supply main atthe start of operations. In such cases, the present valve may beinserted in the supply main ahead of the regulating device and closedand set to open at full pressure. The main is thus kept closed untilfull pressure is built up, when the valve opens automatically andtransmits such pressure. But the invention is of course capable of manyother uses. A

The controlling mechanism and diaphragm are fully enclosed and protectedfrom dirt and injury and may be conven v iently set to operate at anypredetermined pressure, While the parts are rugged in construction,compactly arranged and positive in their operation.

I claim as my invention:
